JavaScript Number Pattern 41

Here`s a program that prints the above number pattern using JavaScript Programming:

example.html
Copied
Copy To Clipboard
<!DOCTYPE html>
<html>
 <head>
  <style>
   div{
    display: inline-block;
    text-align: center;
    width: 30px;
   }
  </style>
 </head>
<body>

<script>
var i, j, k;
var m = 1;
for(i=1; i<=9; i+=2)
{
 for(j=i; j<9; j++)
  document.write("&nbsp;&nbsp;&nbsp;&nbsp;");
 for(k=1; k<=i; k++)
 {
  document.write("<div>" +m*m +"</div>");
  m++;
 }
 document.write("<br>");
}
</script>
</body>
</html>

💻 Testing the Program

When you run the above program, it will print the following output:

Output
                1
            4   9   16
        25  36  49  64  81
    100 121 144 169 196 225 256
289 324 361 400 441 484 529 576 625

🧠 How the Program Works

Let's break down the logic behind the code:

  1. Variable Declarations:
    • i, j, and k are declared as variables to be used as loop control variables.
    • m is initialized to 1, which will be used to generate square numbers.
  2. Outer Loop (for Loop with Variable i):
    • The outer loop runs as long as i is less than or equal to 9, incrementing i by 2 in each iteration.
    • This loop controls the rows of the pattern.
  3. Inner Loop 1 (for Loop with Variable j):
    • The inner loop runs as long as j is less than 9.
    • In each iteration, it adds four non-breaking space (&nbsp;) entities to the HTML document using the document.write function.
    • This loop is responsible for adding the appropriate indentation before each row of numbers.
  4. Inner Loop 2 (for Loop with Variable k):
    • The innermost loop runs from 1 to the current value of i.
    • In each iteration, it adds a <div> element to the HTML document containing the square of the current value of m.
    • After adding the div, m is incremented to prepare for the next square number.
  5. Newline (<br> Tag):
    • After the inner loops complete, a <br> (line break) tag is added to the HTML document using the document.write function. This starts a new line for the next row.
  6. End of Outer Loop:
    • After all iterations of the inner loops are completed for the current value of i, the outer loop increments i by 2 and starts the next iteration.
  7. Final Output:
    • The combined effect of the loops and document.write calls generates a pattern of square numbers with indentation and line breaks.

💯 Tips for Enhancement:

Explore the versatility of this pattern by adjusting its parameters. Whether you increase or decrease the size, tweak the spacing, or modify the characters used, each change opens up a world of possibilities, allowing you to customize and create your unique visual effects.
